The Trinity School of John Whitgift, usually referred to as Trinity School, is a British independent boys' day school with a co-educational Sixth Form, located in Shirley Park, Croydon. Part of the Whitgift Foundation, it was established in 1882 as Whitgift Middle School and was a direct grant grammar school from 1945 until 1968, when it left the scheme. The present name was adopted in 1954, to avoid confusion with Whitgift School. The school's head is now a member of the Headmasters' and Headmistresses' Conference (HMC).
